I actually have access to this full article and just found it recently while doing research for one of my papers and thought it sounded interesting so I downloaded it. I think they did a good job for being a stepping stone into the AB/DL community. I can understand from a research standpoint why they did not include everything into there samples, like babyfurs and sissies, and other people who are apart of this community but were not include, and I'm hoping they are able to do some more research
